MICRONA™ Agricultural Lime corrects low soil pH, is a source of calcium, releases nutrients, maximizes fertilizer effectiveness, activates microorganisms, reduces solubility of heavy metals, and improves soil texture. MICRONA will help your garden or small farm produce results. MICRONA Agricultural Lime is made of pure calcium carbonate that is very finely ground for lightning quick action. Because it is not hydrated, it will not burn you or harm the microbiology of your soil.
